I Put a FAN Inside a FAN | Fan Showdown S5E7

It is time for another fan showdown, today its season 5 episode 7. Have you ever wondered what an Noctua A12x25 would look like inside a Noctua A12x25. Well today is your lucky day because that's what we will be testing. Also, one of the most asked for designs finally gets it's time in the spot light, the Tesla Turbine.

Or even better, have not only the factory-molded A12X25 as a goal poast, but also a *PLA-printed* A12X25 version (maybe even a resin-printed version as well). That way you could compare how *any* fan would do if it was resin-printed (assuming that the layer lines cause similar losses among all fans).

[@NickCombs]

I was interested to see how the fans would rank if we were to value FPM and dBA equally instead of only noting dBA and ranking by pure FPM. I realized then that decibels are logarithmic, so I had to convert those values to linear before we could get a proper weighting. Also, the columns won't line up here because we can't use a monospace font in comments. But you can paste it into a text editor if you want that.

[@MeowO_O]

I'm now a big fan of the small fanfan because the creator was able to think outside the box and put the fanfan inside the box. A truely creative way to reinvent the wheel while keeping the wheel exactly the same as before it was reinvented.

[@leifmessinger]

I bet everyone thought of it already, but I'm the only one who did it. But I bet some serious fan showdowners might have done it and didn't want to submit it because they wanna make "good fans" that are "actually productive". It also seems really low effort (and it kinda was). Just take the fan, scale it down to fit in the fan, scale up the blades to touch the walls, add the hub template, hollow it out, done. The better thing would have been for me to do some cylindrical scaling to make the fans stretch to accommodate the larger hub, but even noctua's mini fans have about the same blade proportions as their big fans.

[@notonlyhuman6073]

Tom’s Dragon Wing fan is insane! Well done, mate!! We need to have a special fan episode where we take all the best parts of of the featured fans over the years, and combine them into an ultimate fankenfan! Imagine the Dragon Wing in a Cheater shroud for instance!

[@pr0xZen]

Certainly - but 40+(++) dba isn't exactly "quiet" for higher end fans.

[@ScytheNoire]

@@pr0xZen His recordings though are not in a proper sound chamber, so they are higher than the true value. So it's only comparable to other fans on the list in that room. Your own personal room and setup will differ. The fan db in a proper sound chamber is only 22.5 db. That's also at full speed, and my fans never reach full speed, since it's not needed. So I never really hear the ten fans, even when gaming for hours. The pump makes more noise.

[@pr0xZen]

@@ScytheNoire If you never run fana at 100%, then comparing fans by manufacturer or lab rating performance metrics is pointless, and seriously misleading at best. At that point, the results and metrics of these "fsn showdown" tests are arguably more representative of deployment in relateable usecase than any of the 1st or typical independ lab party figures.

[@ALifeOfWine]

Now this is a proper fan showdown episode. In hub designs that attempt competition for the original plus a wild card for the lols.

[@Zicrixdoesart]

6db louder though is pretty significant, but it might regain some of that if it was actually made out of Noctua's special material.

[@scarecrow5848]

thats true! or mabye in resin? :))))

[@alexprach]

Well if it was made of the special material it might still be noisy, but since Noctua said they made the material (something crystalline they said) not to warp under temperatures or age, then the fan get closer to the frame have even more performance and probably even noisier. But you could also run the fan slower or not as often because of how performant it is.

[@alexp974]

I would also like to see this fan attached to his variable voltage supply, crank those RPMs up to see if there is indeed increased efficiency.

[@YOEL_44]

I think you all are missing one important thing here, IT'S NOT A FAN, it's designed to be pushed by pressure to generate movement, not to be rotated to move air.

[@salimufari]

Not to mention the rpm needed to make it function even a little bit. I don't think the A12-X25 motor can hit 10k rpm.

[@paradiselost9946]

@@YOEL_44 go read the patent... and whats its current only commercial application? as a pump. i guess the rotary engine aka wankel is designed to be pushed by pressure too? at which end? the rotor? or the shaft? felix originally designed it as, guess what? a pump... yknow, ALL engines are just glorified air compressors? and then theres the whole issue about pressure, velocity, and bernoullis...

Honestly the hard angle on the Dragon Wing has a smooth but more steep curve to it than the original Noctua fan blades. But Noctua's new fan blades yet to be released on their updated 140mm design, also, has a steeper curve; it's more abrupt/jagged of a curve though.

That said, if it was something in a rack in its own shed or basement or something, it can go right ahead and scream.

[@jwilliams703]

I've been a long time fan of the fan showdown. The thing with the a12x25 is its supposed to work in a lot of different configurations. Case fan, heatsink fan, radiator fan. It always does good. Is it the best for anything? not so much but its a great compromise between all kinds of fans. So just pure airflow is not a great way to compare fans. We need to take into account airspeed, CFM, static pressure, lifetime and efficiency.

[@VinayVarsani]

I would really love a sound based series where the dba and potentially a subjective "how nice to listen to" score are the focus. Could make use of the resin printer more and then rank all the fans based on fpm ratio Maybe normalizing with power or so the rpm of each fan is the same?

Not sure the cost of that dissolvable support filament, but there is a cheap and easy way to get easily removable supports for prints: Use a different filament type. If you are printing in PLA, use PETG supports, and if in PETG, use PLA supports. It makes them very easy to remove, and PLA and PETG are usually materials you already have around.

[@jttech44]

PVA filament is very very cheap.

[@DuribunWolf]

@@jttech44 Depending on where you live, PVA filament can cost a far chunk. Right now just looking at general lists, it costs about the same as a full 1kg spool of PLA for a 250g-500g spool of PVA. An while I don't expect people will use it exactly 1:1, that is still not 'cheap' in a price difference for something that only functions as a support material.

[@jttech44]

@@DuribunWolf sure, if you use the cheapest possible PLA, which is a pain to print with.

[@DuribunWolf]

@@jttech44 Which is what the majority of people who 3D print as a hobby will mostly buy. Which is why PVA filament is considered expensive, as really the price per kg even for more expensive PLA is better than you can for PVA.

[@jttech44]

@@DuribunWolf Tbh, most people who are 3D printing don't have dual extruders so, PVA filament isn't something they'd buy. Once you've bought into dual extruder printing, you've figured out that cheap filament prints like crap, and nicer PLA+ makes alot of sense in terms of actual material needed and wasted material.At which point PVA isn't really cost prohibitive.

For a solution that is cheaper than PVA, when the application allows. When printing with PLA use PETG for support material & vice versa. The 2 materials will not bond to eachother at all, so the supports just fall away.

[@nicklaich]

[@pierQRzt180]

Finally someone adding parts that create turbolence at the end of the blade. That's a key to make air turbolent and easiert to push. I think even better would be with an intake that "prepares" the air for the blades. That is, creates turbolent air (with fins) and with curved static blades (like the fan) so that the fan can push as much as possible.

[@willie9899]

Noctua has a new fan on the way, and during their interview with GN about it and the R&D process that took a few years, they stated that their fan isn't optimized for pushing air through a radiator or for raw CFM. They strive for a sort of hybrid between the two styles. They want their fan to work really good as a case fan, and equally as good as an AIO fan. That being said, BY DESIGN, they are beatable with a more specialized design. It SHOULD be beaten in these tests. However, it SHOULD NOT be beaten across both open air and resistant (through radiator) CFM with a single design. I'd love to see how the Dragon Wing would fair against it for open CFM. It would be really cool to see Noctua beaten at their own thing

[@sebastianchalinski4582]

[@zeemon9623]

The Dragon wing is kind of cool but sadly you won't know that once it's spinning. Also there are obviously more dimensions to fan design than cfm/rpm Even noise isn't just noise as there are types of noise that are perceived more quietly. A low frequency hum can be the same dB as a high-mid squeal but the hum will sound quieter. And if both are at low volume to begin with, the difference will be even greater. So it's a doubly good idea to try and get your fan to emit only low frequencies.

[@HDJess]

Noctua is still unbeaten, imo. It's not enough to push more air through, if the acoustics get worse. When someone comes with a fan which is quieter or as quiet as Noctua and still within that 120x120x25mm envelope, I'm sold.

[@jabzilla21]

[@edwardnedharvey8019]

Love the fanfan and the tesla turbine! I think the tesla turbine might actually work, if you put a stationary restricting shroud over the intake. it sucks a little air in through its intake holes, and it projects it outward against the outer rim (pressure on the outer rim) but then it goes equally forward and backward. Just put a lip around the intake side, so the pressure on the outer rim can only go out the exhaust side. I don't have high hopes that it will perform well, but it'll certainly be more than zero!

[@arg8763]

Dragon fan is impressive for fitting completely in the housing.

[@TheRealAlpha2]

I had a nice gigle at the Fan fan and Tesla turbine smoke tests, they really were basically memes, but the second I saw the smoke hit the Dragon wing (07:28) I knew it was going to do well. Just look at how tight that flow is. Sky scoop was a valiant effort.

[@BRUXXUS]

While I enjoy the creative and over the top big designs, I find the ones that stick within stock fan dimensions much more interesting.

[@pino_de_vogel]

i would be verry interested in seeing how the air moves trough a radiator/aircooler. That way you can see if it has some actual air pressure or takes the fastest way out and slows down. And you should scale down the Dragon Wing till it hits the same noise levels and then compare. Then you can see if it actually is better on simmilar noise levels and add the pressure test.

[@estropocky]

I like how harmonic the Dragon Wing was, legitimately 👀Like, I'd deal with the noise (loudness) if it sounded that good.~ I'm glad the fanfan at least did decently for a good joke fan. Little bugger made me happy.

[@Acedemonlord]

[@georgewills-ek1gg]

the fanfan reminded me of the dizzyfan. a friend of mine has this complex, where there are rows and rows of electrical cabinets. each one had a large external case cooling fan much like these except bigger. they run of 12V DC and turn on whenever the units reach a curtain temperature. some of them had failed however. i wonder if he learned his repairing skills from Mcgyver, because of all the Jerry rigging that was in there. for example, a random DC12V blower fan was thrown in to replace one of the original fans. on another unit, a cheap desk fan was just blowing in through the inlet of the old fan and the DC wires were just connected to a 12V lightbulb. last, but not least was the dizzyfan. he had taken a random mains powered motor, slapped it on a bracket in front of the inlet and attached the fan to it. he didn't even cut off the fan's power cable, witch was just whipping around and slapping anything in it's radius, making noise. and to control it, the 12VDC lines were just connected to a 12vdc trigger relay thingy. he had written "dizzyfan controller" on the little box the relay was in, hence the name. you could tell that it was on from the end of the corridor from the distinctive slapping sounds of the cable going round and round. it looked real goofy while it was on too LOL!

We need to revisit the Tesla turbine and add a front shroud with an inlet that restricts the airflow to those inlet vents, and redesign the outlet stator to better redirect the edge flow out the back. But the drive motor is the limiting factor. I've seen a Tesla turbine used as a pump heave gallons of water, but it was hooked to a big 1HP DC motor.

So, if I saw either of those fans in the store, I'd buy that Kenton Baseball T-shirt. Looks good.

The tesla turbine was meant for installation inline and had to be enclosed in order to have its exit port functioning. The stack of its plates were exactly in the same position on top of each other but it also was designed to move a higher density steam. I have seen it used as an inline water pump and it was an excellent as the force of the water leaving it was so high. With the density of air being so much less, the plate stack might need to be at a slight offset from the plate below it forming a spiral pattern of the openings in the center when the plate stack is completed. At what offset to produce the best movement would be up for testing. If the inside of each plate had teeth, the plates could then slide onto a gear affixed to the fan motor shaft for the purpose of being able to change the offset distances until the best distance was achieved. With a gear attached to the fan's shaft, that would also assist the drag to create more spin but only in an enclosure to help create that centrifugal force. Without the enclosure for steam, water or air, the result would be exactly as we saw, exit happened between each plate and stayed close to the fan because the enclosure would assist the air speed build up that would be exiting the blades. This would create higher exiting thrust.

I feel like the fan fan would be really fun to use in a much larger fan. Like a 200mm or something, so that the hub isn't taking up half the blade area

[@leifmessinger]

Yeah The limit then becomes how big of a square can you fit in a circle (big fan hub), and then how big of a circle can you fit into that square (little fan hub).

Blue? That's purple, just like the background lights you have. 💜

The dragon wing makes an interesting chord. Sounds like a car horn. which i think is like a major 3rd?

[@darkangel999]

I would buy the dragon wing. Noctua has the advantage of an well known reputation but better preference would peak my interest enough to at least give it a try and it also looks good 👍.

At last, someone bested Noctua

[@FelanLP]

"Dragon wing" A worthy name for a chosen one.

[@AtariDays80]

Now you need a six petal fan where each petal is a spinning fan. Like those crazy carnival rides.
